hi, i have a:
GT-I9300
AP: I9300XXEMB1
CP: I9300XXEMB1
CSC: I9300XAEMB1
I cannot get any service, whenever i attempt to send a text/make a call i get 'not registered on network' and 'emergency calls only' is constantly shown in the notification bar. (i have searched these forums, and tried everything i could find)
My IMEI and s/n are fine. (same as the box/under battery)
the phone was locked to orange, now unlocked (i think), even when i use an orange sim card i have the problems above (let alone with my giffgaff sim i want to use), both sim cards work in other phones.
i have tried reflashing stock rom/different modems
i have tried ariza's patch: http://forum.xda-developers.com/showthread.php?p=32711954
Service state: Out of service
Roaming: Not roaming
Mobile network state: Disconnected
My phone number: Unknown
Now is there something painfully obviously i have forgotten to try or is there a fault? :silly:
thank you

stock jellybean 4.1.2, clockwordmod recovery 6.0.1.2
i tried to unlock using GalaxSim Unlock. Before i 'unlocked' and put in my giffgaff sim phone asked for network unlock code, after i 'unlocked' i was no longer asked for unlock code so i assumed it had worked.
i cannot actually be 100% sure it worked before unlocking as i brought the phone second hand. do u think ive been had ?

This may be a really stupid question but are you putting the sim in the right way round?

I reckon it's possible. If it's been registered to an insurance company as stolen then you won't get signal in the uk on any network.
Download stock jb firmware from sammobile.
Go to cwm and format system, data and cache. Then go to facrory data wipe.
Then reboot to download mode.
Use odin to flash rom. When it reboots watch it and make sure it applies the csc wirhout failing.
Put the orange sim in and make sure it gets a network.
If it doesnt there is a possibikty u have been had. You could phone orange and ask them if the imei is registered as stolen.

I did literally everything above just before i posted this thread, the phone is reading the sims and recognizing the networks but thats about it.
I'll give orange a call tomorrow, in a way im hoping the IMEI is blocked because it getting frustrating now.
Funny thing is, the reason i brought this phone is the S3 i had before had the same problem, i found out the previous owner had it on contract (sold it to me), upgraded and thus the handset was blocked after the upgrade. I guess i just refuse to believe ive fallen for the same thing twice

Networks shouldn't block the phone because of an upgrade. Orange are still open now. I would give them a call.
I can't see it being anything else when your imei is in tact.

When a phone is upgraded the old phone will still work it is only the old sim that is blocked, a phone is blocked if it is reported lost or stolen.
Have you checked the APN under Settings > More Settings > Mobile Networks > Access Point Names to make sure the correct one is indicated for your sim card. If you are on Orange and o2's APN is ticked it wont work for example..

Try reflashing a radio from sammobile.com/firmware via Odin. That helped me as I had the same problem. (Only I live in Germany and I'm on the network of the German Telekom.).
If that doesn't work, try resetting your flash counter, going back to stock (And here it comes!) and "Upgrading" via Kies. I've seen some cases where that worked.
Hope I could help!

Edit: And try logging onto your carriers (Orange's) network.

[Q] No service error

Hi guys
This is related to my brother's Galaxy S II. He had been using it for a couple of weeks when suddenly (according to him, wouldn't say if he dropped it or anything), he got disconnected from the mobile network.
He rebooted the phone, and got a no service error. When going into Mobile Network settings, it reads 'Insert SIM to access mobile network settings', even with the SIM inserted.
I tried his SIM in his phone - no luck.
I tried my SIM in his phone - no luck.
I tried his SIM in my phone - works.
Tried flashing two new ROMs - no luck.
I suppose this is the phone's SIM reader, then, but have you had any similar problems with it? Do you reckon this will be covered by warranty?
Thanks in advance.
You tried his sim on your phone and no luck? I thought you said his phone is the one wiyh no signal? Anyway, can you still see the imei on his phone?
Sent from my GT-I9100 using xda premium
Yes, I tried his sim on my phone too, just to see if the SIM was broken (which it wasn't). His phone has no signal, that is correct.
IMEI and IMEI SV list 'unknown' in phone info, but on the original boxing it's listed as 358150044627942.
Baseband also Unknown?
Maybe he flashed some custom Roms and lost his imei.
Sent from my GT-I9100 using XDA App
Yes sir, Baseband is also unknown. He wouldn't know how to flash custom ROMs, so I doubt that's the case.
Is this something we can fix ourselves, or would it need shipping off to service?
Thanks.
If you are sure that he doesnt flash any custom rom and only update with KIES you should bring the phone to Sammy support.
You can search the forum and find some threads were people lost their IMEI 'cause they flash custom roms. Then you can recover it when you backuped your EFS.
http://forum.xda-developers.com/showthread.php?t=1261948
But in this case you i think you havent any EFS backup.
My mistake: I had flashed LightningMod to his phone, but he had no problems using it after I flashed it -- the error only appeared after a couple of weeks.
OK, so seems like we're just gonna send it to Samsung, as I'm leaving the country on Tuesday anyway. Have reverted to stock rom and kernel, and I guess we'll blame it on KIES or something. Judging on our past experiences with Samsung it shouldn't be a problem anyway.
Please use the Q&A Forum for questions Thanks

I9300 - No find Networks - IMEI Correct - HELP!

Hi
I bought this S3 in Lituania as a "No Signal" phone hoping that it would work in SPAIN.
I have switched it on today, trying with my own sim and after enter the PIN I see "Only emergency calls". I have uptaded it to the 4.1.2 JB but same result.
Checking the locked status I see all OFF. I rooted and installed the Voodoo Unlocked and same result "Unlocked phone" but no network.
The IMEI is the same in the phone than in the back so It doesn´t look like a IMEI issue...
I applied the ariza_v04.zip patch with same result...
I can see the SIM contacts and the phone recognize my SIM number, I mean in settings I can see my phone number...
More info, when I try to select manualy my network, it doesn´t find any!
Could you please help??
Thanks thanks so much!

Download a stock rom say the new 4.1.2 then go into recover make all wipes. After you have done, while in recovery move it down to chose from sd and don't click anything. Now hold Power + Volume down + Home all at the same time till you go into download mode connect your phone and flash stock unrooted firmware on your phone..
When finished start the phone if there is no signal then download CF Root which Chainfire made and root your phone and download GetRil from android market and see if your modem is matching it will tell you your recommended modem find and download it. Then match the ril if that doesn't work sorry mate you might have a blocked IMEI or a bad phone..
Try with another SIM.

May be the antenna has any problem?
Any other ideas?
IF you have emergency calls available - that would mean the phone has some network in range. Therefore, I doubt if this is antenna issue.
Thread moved to Q & A section, post in the relevant section next time.
Have you tried different SIM cards?
Do emergency calls work? If so your number is blocked. It may be a stolen phone.
Sent from my GT-I9300 using xda app-developers app
Well... news!
I went to the Samsung SAT and... the phone has NO ANTENNA! But not only this, it hasn´t the antenna plug!!
So I guess that if I want to fix it I should:
1- Solder any antenna or any antenna plug and then connect an antenna (too dificult I think...).
2- Find this silicon chip replacement (It´s where the usb dock and the camera conects to). But, where?! I tried but I don´t find it...
Any other idea?
Thanks!!
Can anyone help? Thanks!!

GT-I9300 unlocked, but not quite unlocked?

Yesterday I bought an S3 and rooted it straight away as I was trying to unlock it due to it being on EE. I couldn't do anything and downloaded Galaxsim unlock and paid for an unlock. Now everything shows as unlocked and so far I've tried orange and vodafone both work. I'm trying to get o2 to work with my S3 but it's not working and just says "Network is not registered". It also says invalid MMI when I tried something else I don't quite remember. Any help please?
This is in the UK by the way, I believe the phone is from germany though.

Hello. I typed the code in you told me about, I had done it before it just says "connection problem or invalid MMI code" when I put an orange simcard in and "not registered to network" for o2. The thing UMTS method thing also wont work for me because as soon as I go on network lock it says "menu does not exist current command is 186." The apn settings are all correct.
I'm going to ask again, which version of JB are you using? 4.1.2?? If yes, you need to downgrade to 4.1.1 to use this trick

Sorry man I didn't see your comment at all, yes 4.1.2, so I can't continue to use 4.1.2 or do I downgrade, use the trick then upgrade?
Yep, downgrade to 4.1.1 first, use the Trick (missing option 4 now will be there), unlock & check if works. Once completed, upgrade back to 4.1.2. This method is permanent so in future you can flash any ROM and SimLock won't be back.

No problem final question, does the baseband number really matter too much? I've got an XXELL4 but I can't find one for 4.1.1. Sorry if that seems nooby it's just my first time downgrading
Here you go
Download any similar one, on the bottom of the page you can get 4.1.1
I might be wrong but I don't believe this method will work on non qualcomm devices.
Anyway, no "network unlock code" requested on boot means that your device is not sim locked anymore.
Did you check that your serial number and imei match those written on your box?

Nope. Just shows the same thing it did before "MENU NOT EXIST, current command is 186"
EDIT: If curiosity is killing you guys now, the phone couldn't get unlocked. Not even when I took it to the shop; every simcard worked except o2. They simply gave me another s3 and I was happy

Exactly same problem with JB 4.1.2
I fear if I downgrade I can lost the IMEI, happend some trouble with IMEI with the guy who try to unlock before phone comes to me.
The GalaxSim Unlock shows that the phone is unlock and all ok, but still recieve the "not registered in network" error message with any sim that´s not from the seller company
¿Any ideas for unlock in JB 4.1.2?
Thanks

[Q] clueless

This is the story. S3 bought in europe. stopped working immediatelly(i think. or maybe after some weeks) after. didnt get fixed service had some warranty issue.
When i say didnt work, i meant the telephone-side of the device it didnt recognise the sim. everything else works fine(even wifi)
I live in greece so i had the phone sent to me here in hopes to get it fixed. but before that i asked for it to be unlocked and my cousin supposedly(he s not really that tech savvy) unlocked it by the carrier.(even gave me the number to be sure everything's ok)
I originaly thought it might be a hardware issue cause the sim wasnt recognized(remember that problem happened on the original carrier its not a matter of lock) but the guy i had went to to fix it said the entire gsm part isnt working so its either a SOFTWARE (thats why i m asking help here) problem or the main board should be replaced.(think he tried to restore it even to original firmware)
After a lot of research here and on google i m kinda lost because so many things seem wrong at the same time.
1.when i type *#7465625# it goes to personalization but below that is blank. then after 2 seconds i get " Unfortunately. the processcom.android.phone has stopped." so i cant get info on whether its locked or not
2.when i type *#06# i get IMEI null / null "ok" ... so i cant see if it has the same as its written under the battery..
3.when i try to press the notification "software update" i get registering device... " attention! Processing failed "ok" "... so i cant even update to a (maybe) working patch
4. The sim it uses is micro sim and i dont have one available at the moment. so i only check the progress by dialling 911.(isnt it valid to assume even without a sim it would still dial?"out of service area")

Model Number GT-I9300
Android Version 4.1.2
Baseband Version Unknown
Kernel Version 3.0.31-1042335 [email protected]#1 SMP PREEMPT mon MAR 11 17:32:43 KST 2013 (its like 2 hours before i picked up the phone from the guy who was seeing if he could fix it. does that mean he did something?)

STATUS
Network Unknown
Mobile network type Unknown
Service State Out of service
Roaming Not Roaming
Mobile network state Disconnected
ERI version Unknown
IMEI unknown
Device status Normal
IF this is a software problem i need your help to know where to get started... you have great guides like for the IMEI or the Baseband unknown message but i dont know where to start cause all these happen at the same time and i dont know which are related to the sim not recognised problem or something someone before me did..(forgot to mention the phone is NOT rooted or flashed to whatever. But i m going to do that when i know more about what i need)
ANY help or information on what is it that i m dealing with would be GREATLY appreciated.

But i have the Imei under the battery and i also have the unlock codes from the original carrier.. is there nothing to be done?
Get a microsim and test.
If fails, you can root and flash Samsung firmware again.
Can use s3 toolkit for above.
Come back after these.
Good luck

No. the IMEI is contained within the EFS Folder which is either missing or corrupt. Only a service centre can repair this. The IMEI number must be programmed into the device in order to connect to the network. This is why you cannot.

None of this will help.

[Q] downgrade 4.1.2 please

Bought an I9300 s3 on eBay is locked to O2
Vodafone sim
Spoke to O2 no help at all. Call 202?
Doesn't make calls.
I've got an efs backup but from the 4.1.2 current stock.
Seems this won't downgrade to 4.1.1
Odined the stock 4.1.1 no joy. Won't boot.
Cwm an old miui 4.1.1 also no boot.
Odin back to stock unbranded 4.1.2 boots fine. Rooted cwm triangle away. Fine.
Whos is this phone? Apparently not mine.
How to down grade please?
Any help gratefully appreciated.
Super wipe after flashing rom helps.
Downgrade to 4.1.1 probably won't have SDS fix so may kill your phone.
If it doesn't make calls with O2 sim then IMEI may be blocked. It won't make calls on Vodafone, because it's locked to O2.
You have to factory reset if it wont boot.

So you're saying after cwm the 4.1.1 I should full wipe.
Then the business.
Then flash a safe kernel before upgrading back.
If I just odin the 4.1.2 stock back over surely the brick bug won't activate?
Flash 4.1.1, full wipe. Do your unlocking, flash 4.1.2

This went badly wrong.
Flashed stock region correct. 4.1.1
Flashed chainfire cwm root.
To allow wipe
Booted fine.
The fix as follows doesn't work as the final menu still not available.
Just dial the following keys *#197328640#Main Menu[1] UMTS*[1] Debug Screen*[8] Phone Control*[6] Network Lock*Options [3]Perso SHA256 OFF*(after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in*[6] Network Lock then choose*[4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone
Even though I didn't execute anything as that menu option isn't there something bad happened.
I installed galaxsimunlock from the play store.
It now says invalid imei.
Glad I backed that up.
Still locked.
The saga continues
I would try an O2 sim before anything to see if the phone actually works or not .
Blocked phone are blocked via IMEI and require the blocking network to remove the block .
Report phone stolen network block IMEI get new phone sell the now blocked phone is fairly typical .

If I buy an unlock code on the Web or at a store will it sort of the blocking from the network?
Don't know anyone with a micro sim on O2.
Thanks for your times
Edit.
I flashed back to 4.1.2 its ok. The baseband doesn't get replaced on downgrade and isn't understood by the older software. There is a post somewhere here about it.
This is what causes the odd error messages in that unlock app. Currently says can't read nv
Unlock code will do nothing if the IMEI is blocked, the phone is useless.
Take it to a phone store, for a small fee they will tell you if it is locked or blocked.

Are you now saying the phone is blocked ???
If so return to the seller / Ebay .
Unlock code will not remove blocked IMEI .
Usual reason for a block is phone is stolen

I agree if it turns out to be blocked I will. It was PayPal so he must be verified.
But I still don't know anyone with a micro sim. Shame they're not all the same size now.
I was just checking ahead of time. I don't want to pay £15 for a code and it not work.
I work weekends so I'll have to wait until Monday.
Thanks everyone you're being very helpful. Much appreciated.
Good news everybody!
We've got a delivery to...
- found someone with an O2 micro sim.
Works fine on O2.
Seems I'll have to go pay for a code online or in one of those seedy little shops.
Seems a shame. As I can alter my /efs backup and presumably restore it back.
If only I knew which file/s to change.
It's not the most obvious one that contains only three letters O2U
Unless galaxsimunlock doesn't restore properly.
Galaxsim unlock is fine. But you have to pay now because he removed the beta / free apk from his xda thread

I agree galaxsim unlock would be great. But as it now flashes a red bar
"Unable to read nv data"
And offers no option to unlock or pay. Cos it says in the help that it doesnt know it can unlock the phone.
I'll have to wait for an upgrade.
